ring 16 and is contacted by a clamping flange 26, corresponding to theflange 14 on the inner edge of the Wheel except that this flange isprovided with a round instead of squared opening for the bolt 12 and hasa cupped countersink to accommodate the hemispherical bearing face ofthe nut 13.

In order to assemble a pair of tires and rims such as shown in Fig. 1,the inner clamping flange lat is located, the bolts 12 being passedtherethrough andthrough the telly; neXt the clamping ring 16, which issplit, is located; neXt'the rim 17 containing the tire'is slipped inplace;-then the center hzud 19 is properly positioned. After beingpositioned, the bolts 2% are located with the nuts 23 seated in theslots 22; next the rim 21 is slipped in place and this is followed bythe outer clamping ring 25, which is also split. The clamping flange 26and the nuts 13 on the bolts 12 complete the assembling. The nuts 13 arethen screwed home and the operation is'complete. The tires are removedby reversing the operations just described. It will be seen that thetightening process is equalized as to both rims; that is, a forcetending to clamp the two rims against the center bolt 16 is appliedequally to both tires due to the'fact that the centering ring isproperly centered and immovable transversely before thetighteningprocessbegins. This, as heretofore described, is particularlyadvantageous and results in uniformity of wear and transmission of load.

It is obvious that modifications may be made in the construction shownand such modifications I consider within the scope of my invention.

a I claim:

1. In a dual tread wheel, the combination of a felly, a split centeringring having an elongated aperture therein, a removable stop projectedthrough said telly and into said aperture, said stop holding said ringagainst transverse movement. but permitting limited circumferentialmovement, a pair of rims, and means for clamping said rims against saidcentering ring, substantially as described. x

2. In a wheel, the combination of a felly, a split centering ring havinga plurality of apertures therein, bolts projecting through said fellyinto said apertures and arranged whereby said centering ring is heldagainst transverse movement-but permitted limited relativecircumferential movement, a pair of tire rims having portions contactingsaid centering ring and means for clamping said rims on said felly,substantially as described.
